ACCESSORIES SUPPLIED KRA 405B SYSTEM COMPONENTS as required The greatest single contributor to increased reliability of all modern day avionics is to limit the maximum operating temperature of the individual units whether panel mounted or remote mounted While modern day individual circuit designs consume much less electrical energy watts per cubic inch dissipated within the avionics unit remains much the same due to the high density packaging techniques utilized Consequently the importance of providing cooling to the avionics stack is still with us today While each individual unit may or may not require forced air cooling the combined heat load of several units operating in a typical avionics location will significantly degrade the reliability of the avionics if provisions for cooling are not incorporated in the initial installation Failure to provide cooling to the equipment will lead to increased avionics maintenance costs and may also void the Honeywell warranty CONFIGURABLE PARAMETERS The installer may alter some of the operational characteristics of the KRA 405B by installing a CM 2000 Configuration Module that has been programmed with customized preferences These characteristics are the threshold altitudes for the three Altitude Trip Points and a selectable offset to be applied to all altitude outputs If these parameters are inconsequential to the installation or the factory presets are acceptable the CM 2000 should not be
